Ethyl 1-[(2-chloro-1,3-thia-zol-5-yl)methyl]-5-methyl-1H-1,2,3-triazole-4-carboxylate

In the title compound, C(10)H(11)ClN(4)O(2)S, the triazole ring carries methyl and ethoxy-carbonyl groups and is bound via a methyl-ene bridge to a chloro-thia-zole unit. There is also evidence for significant electron delocalization in the triazolyl system. Intra- and inter-molecular C-H⋯O hydrogen bonds together with strong π-π stacking inter-actions [centroid-centroid distance 3.620 (1) Å] stabilize the structure.
